First, the configuration on which the data storage system according to the embodiment of the present disclosure is based will be described. In a data recording device that records detection data from sensor elements, etc., a so-called data logger, the detected data is stored in the internal memory of the data recording device or sent to a communication device equipped with a large-capacity memory, a so-called server, etc. be done. For example, a technique is known in which detection data is transferred from an internal memory of a data recording device to a large-capacity memory of a communication device main body by non-contact communication.

However, in a portable sensor or the like equipped with a data recording device, the data recording device is not always in a communication environment where it can be connected to the main body of the communication device. That is, when a portable sensor equipped with a data recording device is being transported, when the portable sensor and the main body of the communication device are far apart, there is a wall or the like between the portable sensor and the main body of the communication device that prevents communication. If there is something that becomes a barrier to communication, the communication environment will no longer allow the portable sensor to be connected to the main body of the communication device. Furthermore, a large amount of detected data must be stored in the internal memory of the data recording device, which has a limited memory capacity.

Therefore, in a communication environment where the data recording device and the communication device main body can be connected, it is necessary to manually transfer the detection data stored in the internal memory of the data recording device to the large capacity memory of the communication device main body. The detection data must be manually transferred to the large capacity memory before the internal memory runs out of capacity, so in systems where detection data must be transferred frequently, such as systems that constantly sense and continue to store the detection data, Frequent manual transfer of detection data requires a lot of effort from the operator.

Furthermore, in a system that constantly senses and stores detected data, if the data recording device is not in a communication environment that allows connection to the communication device main body, the detected data will continue to be stored in the internal memory of the data recording device. Memory may overflow and become insufficient. Therefore, it is necessary for workers to periodically check whether they continue to monitor the capacity status of the internal memory of the data recording device, and to manually transfer detected data as soon as a connectable communication environment is restored. be. That is, it is necessary for the operator to continuously monitor and periodically check the capacity status of the internal memory of the data recording device.

Therefore, there is a need for a data storage system configured to save time and effort in data transfer processing, and a data storage method that saves time and effort in data transfer processing.

Hereinafter, a data storage system and a data storage method according to an embodiment of the present disclosure will be described using the drawings.

<Data storage system>
FIG. 1 is a block circuit diagram showing the electrical configuration of a data storage system 300 according to an embodiment of the present disclosure. In FIG. 1, thick arrows indicate the flow of data, and thin arrows indicate the flow of control signals.

The data storage system 300 of this embodiment includes a data recording device 100 including a first communication module 10 for non-contact communication, and a second communication module 50 for non-contact communication between the first communication module 10, The data recording device 100 includes a communication device main body 200 that outputs a data transmission start request signal and stores data, and the data recording device 100 has a first storage section that stores data to be transmitted from the first communication module 10 to the second communication module 50. 20, and a first control unit 30 that controls the first communication module 10 to start transmitting data based on the data transmission start request signal transmitted from the communication device main body 200 to the data recording device 100. , the first control unit 30 starts transmitting data from the first communication module 10 to the second communication module 50 when contactless communication between the first communication module 10 and the second communication module 50 is possible. This is a configuration that allows

In the data storage system and data storage method of the present disclosure, non-contact communication refers to communication methods such as wireless communication using radio waves (electromagnetic waves), visible light communication using visible light, infrared communication, and ultrasonic communication, This is a communication method that performs communication between communication devices without using mechanical contacts or coupling parts such as communication cables. Hereinafter, in this embodiment, a case where the non-contact communication is wireless communication will be described.

The first communication module 10, the first storage section 20, and the first control section 30 are electrically connected. Further, the communication device main body 200 may further include a second storage section 60 and a second control section 70, and the second communication module 50, the second storage section 60, and the second control section 70 are electrically connected. be done.

The data recorded by the data recording device 100 may be various data such as image data, acoustic data, audio data, temperature data, humidity data, brightness data, illuminance data, and electrical resistance data.

The data recording device 100 may be a device that acquires data such as the temperature of a detected object such as a cell cultured in a culture medium using a sensor or the like, and temporarily records (saves) the data, for example. This is a device called a wireless sensor chip, wireless sensor device, etc. The communication device main body 200 may be a device that receives and stores data transmitted from the data recording device 100, such as a server, a personal computer, a communication device with a large capacity memory, or the like. The data recording device 100 and the communication device main body 200 may be separate devices, and may be placed on separate substrates, for example. The substrate is made of an electrically insulating material such as glass, plastic, ceramics, etc., and may be realized as a plate-shaped body having a rectangular or circular shape in plan view. Further, the substrate may be translucent, or may be colored black, brown, or the like.

For example, the data recording device 100 is formed directly on the first surface (for example, the upper surface) or the second surface (for example, the lower surface) of the first substrate by a thin film forming method such as a CVD (Chemical Vapor Deposition) method. It may be arranged as follows. Further, an inorganic insulating layer made of silicon oxide (SiO ₂ ), silicon nitride (Si ₃ N ₄ ), etc., an organic insulating layer made of acrylic resin, polycarbonate, etc., on the first surface or the second surface of the first substrate, etc. An insulating layer is formed and arranged by a thin film forming method such as a CVD method. A first communication module 10, a first storage section 20, and a first control section 30 are arranged on the insulating layer. Further, in the communication device main body 200, the second communication module 50, the second storage section 60, and the second control section 70 may be arranged on a second board configured similarly to the first board. Alternatively, the communication device main body 200 may be an independent device such as the above-mentioned server.

The first communication module 10 may include a first antenna for wireless communication, and the second communication module 50 may include a second antenna for wireless communication. In that case, electrodes, wiring, connection conductors such as through holes, circuits, etc. that constitute the first antenna are arranged on the first surface, the second surface of the first substrate, on the insulating layer, and between the plurality of insulating layers. Electrodes, wiring, connection conductors such as through holes, circuits, etc., which constitute the second antenna, can be arranged on the first and second surfaces of the second substrate, on the insulating layer, and between the plurality of insulating layers. can do. Thereby, the first antenna, the second antenna, other circuits, etc. can be integrated and arranged on the first substrate and the second substrate, and the area of the substrate can be reduced. In addition, when connecting conductors such as electrodes, wiring, through holes, circuits, etc. are arranged between multiple insulating layers, for example, the object to be measured on which the data recording device 100 is arranged is a corrosive one such as an acidic culture solution. Even if it is, the data recording device 100 can be placed in the object to be measured with high corrosion resistance.

The first antenna and the second antenna may be realized by, for example, a loop antenna or a dipole antenna. The first antenna and the second antenna may preferably be loop antennas whose antenna lengths can be easily adjusted and which have high reception sensitivity.

The first storage unit 20 and the second storage unit 60 can store programs and data. The first storage unit 20 and the second storage unit 60 may also be used as work areas for temporarily storing processing results. The first storage unit 20 and the second storage unit 60 include recording media. The recording medium may include any non-transitory storage medium, such as semiconductor storage media and magnetic storage media. Further, the first storage unit 20 and the second storage unit 60 may include multiple types of storage media. The first storage unit 20 and the second storage unit 60 may include a combination of a portable storage medium such as a memory card, an optical disk, or a magneto-optical disk, and a storage information reading device. The first storage unit 20 and the second storage unit 60 may include a storage device used as a temporary storage area, such as a RAM (Random Access Memory).

In the data storage system and data storage method of the present disclosure (first disclosure), the data transmission start request signal is configured to be transmitted from the second communication module 50 to the first communication module 10, and the first control The unit 30 may determine that contactless communication is possible when the first communication module 10 receives the data transmission start request signal. In this case, the first storage unit 20 stores data to be transmitted from the first communication module 10 to the second communication module 50, and further stores a data transmission start signal corresponding to the data transmission start request signal. good. When the first communication module 10 receives the data transmission start request signal, the first control unit 30 may determine that contactless communication is possible and start data transmission. Alternatively, when the first communication module 10 receives the data transmission start request signal, the first control unit 30 determines that contactless communication is possible, and the first communication module 10 sends the data transmission start request signal to the second communication module 50. may be sent once, and then data transmission may be started. The second storage unit 60 stores the data, time information, and ID information of the data recording device received by the second communication module 50.

In the data storage system and data storage method of the present disclosure, the "data transmission start request signal" refers to, for example, automatic transmission of data stored in the first storage unit 20 from the first communication module 10 to the second communication module 50. Represents a signal to start. When the first communication module 10 receives the data transmission start request signal from the second communication module 50, the data transmission start request signal transfers the data stored in the first storage unit 20 from the first communication module 10 to the second communication module 50. It may also be a signal for automatically starting transmission to the module 50. Further, the data transmission start request signal is stored in the first storage unit 20 based on at least one of time information and ID information regarding data transmission, which the second communication module 50 receives from the first communication module 10. The signal may be a signal for automatically starting transmission of the data from the first communication module 10 to the second communication module 50.

In the data storage system of the present disclosure (second disclosure), the first storage unit 20 stores data to be transmitted from the first communication module 10 to the second communication module 50, and also requests to start transmitting data. The data transmission start application signal may be stored. The “data transmission start application signal” represents, for example, a signal for automatically starting transmission of data stored in the first storage unit 20 from the first communication module 10 to the second communication module 50. The data transmission start application signal transmits the data stored in the first storage unit 20 from the first communication module 10 to the second communication when the second communication module 50 receives the data transmission start application signal from the first communication module 10. It may also be a signal for automatically starting transmission to the module 50. In this case, when the second communication module 50 receives the data transmission start request signal from the first communication module 10, the second communication module 50 transmits a data transmission start permission signal to the first communication module 10. When the first communication module receives the data transmission start permission signal, the first control unit 30 may determine that contactless communication is possible and start data transmission. Further, the data transmission start application signal is stored in the first storage unit 20 based on at least one of time information and ID information regarding data transmission, which the second communication module 50 receives from the first communication module 10. The signal may be a signal for automatically starting transmission of the data from the first communication module 10 to the second communication module 50.

"Automatically starting data transmission" is not particularly limited, but for example, data stored in the first storage unit 20 can be transferred from the first communication module 10 to the first communication module 10 without any manual work by the operator. 2 indicates that transmission to the communication module 50 will begin via non-contact communication.

"Time information" is not particularly limited, and represents, for example, the time when data started to be stored in the first storage unit 20, the time when the data was stored, the time when storage of the data was stopped, etc.

"ID information" is not particularly limited, but may be a code for identifying the data recording device 100, and represents, for example, a unique number of the data recording device 100.

In the data storage system and data storage method of the present disclosure, the second communication module 50 may periodically transmit a data transmission start request signal to the first communication module 10. Periodically transmitting the data transmission start request signal means repeatedly transmitting the data transmission start request signal at fixed time intervals such as 1 second, 1 minute, 1 hour, or 1 day, for example.

Further, when the remaining capacity (or free capacity) of the first storage unit 20 provided in the data recording device 100 reaches a predetermined value (for example, the remaining capacity is 50%), a data transmission start request signal is sent to the first communication module 10. It may also be possible to start transmitting to. Then, the data transmission start request signal may be transmitted to the first communication module 10 each time the remaining capacity reaches 40%, 30%, 20%, and 10%. This makes it easy to prevent the first storage unit 20 from overflowing due to insufficient capacity. Monitoring of the remaining capacity of the first storage unit 20 by the communication device main body 200 is performed by storing correlation data between the elapsed time from the start of driving of the data recording device 100 and the remaining capacity of the first storage unit 20 in the second storage unit 60. A table may be stored and the remaining capacity of the first storage unit 20 may be estimated from the elapsed time. When the data transmission from the first communication module 10 to the second communication module 50 is completed, a data transmission start request signal is sent until the remaining capacity of the first storage unit 20 reaches a predetermined value (for example, the remaining capacity is 50%). The transmission of the information to the first communication module 10 may be suspended.

As described above, in the case where the second communication module 50 transmits the data transmission start request signal to the first communication module 10 at time intervals, contactless communication is performed when the first data transmission start request signal is transmitted. If contactless communication is not possible and a state in which contactless communication is impossible continues, the next second data transmission start request signal, then the third data transmission start request signal, etc. are transmitted sequentially. The time interval (referred to as Ty1) between the first data transmission start request signal and the second data transmission start request signal is equal to the time interval between the second data transmission start request signal and the third data transmission start request signal. It is preferable that it be longer than the time interval (assumed to be Ty2). In other words, it is preferable that Ty2 be shorter than Ty1. That is, it is preferable to sequentially shorten the time interval between transmissions until non-contact communication becomes possible, such as Ty1>Ty2>Ty3>...>Tyn (n is an integer of 2 or more). In this case, the chances of contactless communication becoming possible increase sequentially, that is, the probability that contactless communication becomes possible gradually increases, making it easier to prevent the first storage unit 20 from overflowing due to lack of capacity. Become.

For example, the above-mentioned time interval may be sequentially reduced to 1/2 of the previous time interval, but is not limited to this value. This configuration can be said to be control that exponentially shortens the time interval. The exponential function in this case is expressed, for example, by f(x)=a ^x (a is a constant of 0<a<1, such as 0.5, and x is a variable, which is time or number of times). Alternatively, the above-mentioned time interval may be shortened in terms of polynomial time. Polynomial time is expressed by a function such as f(x)=x ^b (b is a negative integer, for example -2), and represents a slower change than an exponential function. Furthermore, the control for shortening the time interval polynomially and the control for shortening it exponentially may be combined. For example, the first half (for example, about 30% to 70% of the whole) is controlled to be shortened polynomially, and the second half (for example, about 70% to 30% of the whole) is shortened exponentially. It is also possible to implement sudden control that increases the number of times. In this case, the probability that contactless communication will be possible increases in the second half.

Further, the second communication module 50 may transmit the data transmission start request signal to the first communication module 10 by increasing the signal length sequentially until contactless communication becomes possible. In this case, the chances of contactless communication becoming possible increase sequentially, that is, the probability that contactless communication becomes possible gradually increases, making it easier to prevent the first storage unit 20 from overflowing due to lack of capacity. . For example, the signal length may be sequentially increased to twice the previous signal length, but the signal length is not limited to this value. This configuration can be said to be control that increases the signal length exponentially. The exponential function in this case is expressed, for example, by f(x)=a ^x (a is a constant of 1<a, for example 2, and x is a variable, which is time or number of times). Alternatively, the signal length may be increased in terms of polynomial time. Polynomial time is expressed by a function such as f(x)=x ^b (b is a positive integer, for example 2), and represents a change more gradual than an exponential function. Further, the control for increasing the signal length polynomially and the control for increasing the signal length exponentially may be combined. For example, the first half (for example, about 30% to 70% of the whole) is controlled slowly by increasing the polynomial time, and the second half (for example, about 70% to 30% of the whole) is lengthened exponentially. It is also possible to perform sudden control such as In this case, the probability that contactless communication will be possible increases in the second half.

Further, the second communication module 50 may transmit a data transmission start request signal to the first communication module 10 with the signal strength gradually increased until contactless communication becomes possible. In this case, since the probability that contactless communication becomes possible gradually increases, it becomes easier to prevent the first storage unit 20 from overflowing due to insufficient capacity. For example, if the data recording device 100 and the communication device main body 200 are far apart, for example, if they are separated by several tens of meters to several hundred meters or more, it becomes difficult for the data transmission start request signal to reach the first communication module 10. Even in such a case, the probability that contactless communication will be possible increases gradually. For example, the above signal strength may be successively increased to twice the previous value, but is not limited to this value. This configuration can be said to be control that increases the signal strength exponentially. The exponential function in this case is expressed, for example, by f(x)=a ^x (a is a constant of 1<a, for example 2, and x is a variable, which is time or number of times). Alternatively, the signal strength may be increased polynomially over time. Polynomial time is expressed by a function such as f(x)=x ^b (b is a positive integer, for example 2), and represents a change more gradual than an exponential function. Further, control for increasing the signal strength polynomially over time and control for increasing it exponentially may be combined. For example, the first half (for example, about 30% to 70% of the whole) is controlled slowly by increasing the polynomial time, and the second half (for example, about 70% to 30% of the whole) is increased exponentially. It is also possible to perform sudden control such as In this case, the probability that contactless communication will be possible increases in the second half.

In addition, the second communication module 50 transmits a data transmission start request signal to the first communication module 10 at successively lower frequencies (sequentially longer wavelengths) until contactless communication becomes possible. Good too. In this case, even if there is an obstacle such as a wall that impedes communication between the data recording device 100 and the communication device main body 200, data transmission can be performed by sequentially increasing the wavelength of the data transmission start request signal. The probability that the start request signal will overcome or detour around the obstacle is increased. As a result, the probability that non-contact communication becomes possible increases gradually, making it easier to prevent the first storage unit 20 from overflowing due to insufficient capacity. For example, the above-mentioned frequency may be sequentially reduced to 1/2 of the immediately preceding frequency, but is not limited to this value. This configuration can be said to be control that lowers the frequency exponentially. The exponential function in this case is expressed, for example, by f(x)=a ^x (a is a constant of 0<a<1, such as 0.5, and x is a variable, which is time or number of times). Alternatively, the frequency may be shortened in terms of polynomial time. Polynomial time is expressed by a function such as f(x)=x ^b (b is a negative integer, for example -2), and represents a slower change than an exponential function. Furthermore, the control for decreasing the frequency polynomially and the control for decreasing the frequency exponentially may be combined. For example, the first half (for example, about 30% to 70% of the whole) is controlled slowly by polynomial time, and the second half (for example, about 70% to 30% of the whole) is lowered exponentially. It is also possible to perform sudden control such as In this case, the probability that contactless communication will be possible increases in the second half.

The data recording device 100 may include a large-capacity auxiliary storage device in order to prevent the first storage section 20 from overflowing due to insufficient capacity. The auxiliary storage device may be a semiconductor storage device such as a semiconductor memory card or a semiconductor memory element having RAM, a magnetic storage device such as a magnetic disk, an optical storage device such as an optical disk, or a magneto-optical storage device such as a magneto-optical disk. . For example, if contactless communication is not possible when the first storage unit 20 runs out of free space, the data stored in the first storage unit 20 is transferred to an auxiliary storage device and temporarily stored. The temporarily stored data is transferred to the communication device main body 200 when contactless communication becomes possible. Temporary storage may be controlled by the first control unit 30.

A plurality of controls among the above-mentioned controls to sequentially shorten the time interval, control to sequentially lengthen the signal length, control to sequentially increase the signal strength, and control to sequentially lower the frequency may be executed.

A repeater may be provided between the data recording device 100 and the communication device main body 200 for the purpose of facilitating a communication environment in which the data recording device 100 can be connected to the communication device main body 200. The repeater may be installed in a transport means such as a tray, multiple trays, wagon, or automobile that transports one or more data recording devices 100. Further, the repeater may be installed on an antenna, a telephone pole, etc. on the premises of a facility such as an experimental facility, a research facility, or a storage facility. Further, the repeater may be installed in a building in the aforementioned facility, a room within the building, or the like. Further, the repeater may be installed in an airborne device such as a drone that can hover or fly in the air. Further, the repeater may have a function of increasing the signal strength of data transferred from the data recording device 100 to the communication device main body 200.

Further, the first storage unit 20 may be configured to perform compressed storage of data in the data recording device 100 when the free space becomes less than a predetermined value (for example, 50%). For example, the compressed storage of data is the following operation. When data is stored with an address attached, the data is stored for each address from the first address to the nth address (n is an integer of 2 or more). After the first storage unit 20 has finished storing each data of the first address to the n-th address, if there is free space, it continues to store each data of the first address to the n-th address for the second time. When this operation is performed m times (m is an integer of 2 or more), data with the same value as the first time is not stored at the same address from the second time onwards. That is, compressed storage can be performed at the same address by storing only data with a different value from the first time from the second time onward. The first control unit 30 may control the compressed storage.

Further, compressed storage may be performed by the following operation. For example, if the number of bits of one piece of data is 8 bits, low-level (low capacity) data that does not use all 8 bits (for example, data that can be stored in 4 bits) should be stored in 4 bits. You can also do this. The first control unit 30 may determine the capacity (number of bits) of one piece of data.

The control of the compressed storage described above may be performed by a machine learning model constructed using a neural network program (also referred to as a multilayer perceptron program), a so-called artificial intelligence (AI) program. The machine learning model may be a deep learning model. The learning data (also referred to as teacher data) for constructing a machine learning model may include the storage capacity of the first storage unit 20, which is the total storage capacity. In addition, the learning data is the compressed capacity or compression of each data from the 1st address to the nth address from the second time (second round) onwards, for each data from the first address to the nth address in the first time (first round). It may also include a percentage. The compressed capacity is the capacity of non-stored data that is not stored in one round because it has the same value as the first time, and is expressed in the number of bits, the number of bytes, etc. The compression ratio is the ratio of the non-storage data capacity to the total storage data capacity when there is no non-storage data (when no compressed storage is performed) (non-storage data capacity)/(total storage data capacity) in one cycle. capacity). When the compression ratio is high, it means that there is a lot of data with the same value as the first time, and it means that the change in data is small. When the compression ratio is small, it means that there is little data with the same value as the first time, and it means that the change in data is large. The compression ratio may be expressed as the ratio of the non-storage data capacity to the storage data capacity (non-storage data capacity)/(storage data capacity) in one round.

The compression ratio may be approximately constant, may vary linearly, or may vary non-linearly as the rounds of data acquisition overlap. In other words, by using a machine learning model, we can autonomously discover the conditions of data changes, laws and rules such as the rate of fluctuation of data changes from time-series data of compression ratios, and predict data changes. It can be carried out. The time-series data of the compression ratio may be collected during the entire period of data acquisition during which compressed storage is performed, but during a part of the data acquisition period during which compressed storage is performed, for example, when the free space of the first storage unit 20 is The period may be within a predetermined range (for example, 50% or less and 40% or more).

The learning data also includes the data acquisition time (referred to as T1) required for data acquisition and the time required for compression control when the first storage unit 20 runs out of free space, that is, when the storage operation for the entire capacity is completed. The compression control time (referred to as T2), the data transfer time (referred to as T3), and the restoration time (referred to as T4) for restoring the compressed data to display it on an image device or the like. The data acquisition time T1 becomes longer because the more compressed storage is performed, the more the number of cycles (the number of data acquisition times) increases. The compression control time T2 becomes longer as compression storage is performed. Since the storage capacity of the first storage unit 20 is constant, the data transfer time T3 is constant regardless of compressed storage. The more compressed storage is performed, the longer the restoration time T4 becomes.

Based on the storage capacity of the first storage unit 20, the compression ratio, and T1 to T4, the efficiency of the operation from data acquisition to display can be improved. The operating efficiency when compressed storage is not performed (denoted as Ed1) is expressed as Ed1=(number of rounds of data acquisition)/(T1+T3), and the operational efficiency when compressed storage is performed (denoted as Ed2) is expressed as Ed2= It is expressed as (number of rounds of data acquisition)/(T1+T2+T3+T4). Using a machine learning model, based on changes in the compression ratio and Ed1 and Ed2, determine which is more efficient: the action of not performing compressed storage (referred to as action 1) or the action of performing compressed storage (referred to as action 2). In other words, it can be determined which one has the largest number of rounds of data acquisition per unit time. Thereby, the more efficient operation can be selected between operation 1 and operation 2.

Furthermore, when selecting operation 2 using a machine learning model, it is possible to infer the most efficient time point to start compressed storage. For example, it is possible to infer at which point it is most efficient to start compressed storage among the points in time when the free capacity of the first storage unit 20 reaches 90% to 10%, and to start compressed storage at the point obtained by the inference. You can start.

A neural network program for constructing a machine learning model may be stored in the data recording device 100 or the communication device main body 200, or may be stored in an external control device or the like. The number of layers (the number of hidden layers) of the multilayer perceptron program, which is a neural network program, may be approximately several tens of layers or more, and may be 100 or more layers or 1000 or more layers as necessary. The number of learning data may be approximately 1000 or more, and may be 10,000 or more, or 100,000 or more as necessary.

The data storage system of the second disclosure may also adopt a configuration similar to the above. That is, the first communication module 10 may transmit the data transmission start application signal to the second communication module 50 at time intervals, and in this case, when the first data transmission start application signal is transmitted, the contactless If communication is not possible and the state where contactless communication is not possible continues, the next second data transmission start application signal, then the third data transmission start application signal, etc. are transmitted sequentially. , the time interval (referred to as Ts1) between the first data transmission start application signal and the second data transmission start application signal is the same as that of the second data transmission start application signal and the third data transmission start application signal. It is preferable that it be longer than the time interval between (Ts2). In other words, it is preferable that Ts2 be shorter than Ts1. That is, it is preferable to sequentially shorten the time interval until non-contact communication becomes possible, such as Ts1>Ts2>Ts3>...>Tsn (n is an integer of 2 or more). In this case, it becomes easier to prevent the first storage unit 20 from overflowing due to insufficient capacity.

In the case where the second communication module 50 periodically transmits a data transmission start request signal to the first communication module 10, contactless communication is not possible when transmitting the first data transmission start request signal, When transmitting the next second data transmission start request signal, the strength (also referred to as output, level, or amplitude strength) of the second data transmission start request signal is greater than the strength of the first data transmission start request signal. You can do it like this. In this case, even if the data recording device 100 and the communication device main body 200 are far apart, for example, several tens of meters to several hundred meters or more apart, contactless communication is easily possible. In a similar case, the wavelength of the second radio wave as the second data transmission start request signal may be longer than the wavelength of the first radio wave as the first data transmission start request signal. . In this case, even if there is an obstacle to radio waves between the data recording device 100 and the communication device main body 200, the second radio wave with a long wavelength can easily reach the communication device main body 200 by diffracting and bypassing the obstacle. Therefore, there is an effect that non-contact communication is easily possible. Furthermore, the intensity of the second data transmission start request signal is greater than the intensity of the first data transmission start request signal, and the wavelength of the second data transmission start request signal is the wavelength of the first data transmission start request signal. It may be made longer than that. In this case, there is an effect that non-contact communication becomes more easily possible.

Furthermore, if contactless communication is not possible when the second data transmission start request signal is transmitted, the same operation as above is performed for the second data transmission start request signal and the third data transmission start request signal. It can be executed. That is, the same operation as above may be repeated until contactless communication becomes possible, in which the signal strength is sequentially increased and/or the signal wavelength is sequentially lengthened. You can.

The data storage system of the second disclosure may also adopt a configuration similar to the above. That is, the first communication module 10 may periodically transmit a data transmission start application signal to the second communication module 50, and in that case, when transmitting the first data transmission start application signal, the contactless When communication is impossible and the next second data transmission start application signal is to be transmitted, the strength of the second data transmission start application signal is made greater than the strength of the first data transmission start application signal. Good too. Further, the wavelength of the second radio wave serving as the second data transmission start application signal may be longer than the wavelength of the first radio wave serving as the first data transmission start application signal. Furthermore, the intensity of the second data transmission start application signal is greater than the intensity of the first data transmission start application signal, and the wavelength of the second data transmission start application signal is the wavelength of the first data transmission start application signal. It may be made longer than that. These have the effect that non-contact communication is easily possible.

Furthermore, if contactless communication is not possible when the second data transmission start application signal is transmitted, the same operation as above is performed for the second data transmission start application signal and the third data transmission start application signal. It can be executed. That is, the same operation as above may be repeated until contactless communication becomes possible, and the signal strength is gradually increased and/or the signal wavelength is gradually lengthened. You can.

Further, in order to prevent the first storage unit 20 from overflowing due to insufficient capacity, the data recording device 100 may include a plurality of first storage units 20. One of the plurality of first storage units 20 can be used primarily, and the others can be used as backup in case an overflow occurs.

Further, the first communication module 10 transmits data to the second communication module 50 when it is in a communication environment in which it can receive a data transmission start request signal. The communication environment in which the data transmission start request signal can be received is when the data recording device 100 is being transported, when the data recording device 100 and the communication device main body 200 are remote, and when the data recording device 100 and the communication device main body 200 are This corresponds to a case where there is no communication environment in which reception is impossible, such as when there is a barrier such as a wall to communication.

Further, a relay device may be placed between the data recording device 100 and the communication device main body 200 in order to ensure that the first communication module 10 is in a communication environment where it can receive the data transmission start request signal as much as possible. Further, the relay device may be connected to at least one of the data recording device 100 and the communication device main body 200 via a communication cable or the like, so that contact communication is possible. For example, if there is a relay device near the place where the data recording device 100 is placed or in the room where the data recording device 100 is placed, and the relay device and the communication device main body 200 are connected by a communication cable, the data Even if the recording device 100 is moved or transported, if the data recording device 100 is not remote from the relay device or if the data recording device 100 does not leave the room where the relay device is located, the first communication module 10 This makes it easy for the user to be in a communication environment where the data transmission start request signal can be received. The relay device may be a router, a smartphone, a smart watch, etc. used for wireless communication and wired communication of a personal computer (PC). The communication cable may be a telephone line, fiber optic cable, or the like.

FIG. 2 shows an example of contactless communication of the data storage system 300 according to the embodiment of the present disclosure. In FIG. 2, a bidirectional arrow represents non-contact communication, and an arc arrow represents that data is stored only in the first storage unit 23 of the data recording device 103.

As shown in FIG. 2, when some of the data recording devices are not capable of contactless communication, that is, the data recording devices 101 and 102 are capable of contactless communication with the communication device main body 200, and the data recording device 103 is capable of contactless communication with the communication device main body 200. 200, the data stored in the first storage units 21, 22 of the data recording devices 101, 102 is transmitted to the communication device main body 200; The data stored in the first storage unit 23 is not transmitted to the communication device main body 200.

Next, when all the data recording devices become capable of contactless communication, that is, in addition to the data recording devices 101 and 102, the data recording device 103, which was not capable of contactless communication, becomes capable of contactless communication. The data stored in the first storage unit 23 of the data recording device 103 is automatically transmitted to the communication device main body 200.

The first control unit 30 determines that contactless communication is possible when the first communication module 10 receives the data transmission start request signal from the second communication module 50.

A data storage system 300 of the present disclosure includes a plurality of data recording devices 101, 102, 103, and a communication device main body 200 includes a plurality of data recording devices 101, 102, 103 among the plurality of data recording devices 101, 102, 103. 103 at predetermined intervals to determine whether or not contactless communication is possible. It may further include a second control unit 70 that controls the second communication module 50 to transmit a data transmission start request signal to the first communication module 10.

In the data storage system 300 of the present disclosure, the "predetermined period" is not particularly limited, but represents a period until the capacity of the first storage unit 20 of the data recording device 100 runs out. As described above, the period may be, for example, a period from the start of driving of the data recording device 100 until the remaining capacity of the first storage unit 20 reaches 50% or the like.

Further, the first storage unit 20 may store time information regarding data transmission and ID information of the data recording devices 101, 102, and 103.

When determining that contactless communication is possible, the first control unit 30 transmits at least one of time information regarding data transmission and ID information of the data recording devices 101, 102, and 103 to the second communication module 50. The first communication module 10 may be controlled to do so.

The communication device main body 200 may further include a second storage unit 60 that stores data, time information, and ID information that the second communication module 50 receives.

In the data storage system 300 of the present disclosure, the communication device main body 200 may be configured to perform contactless communication with a plurality of data recording devices 101, 102, and 103 simultaneously. In this case, the time required for drive control of the plurality of data recording devices 101, 102, 103, acquisition of measurement data, etc. is significantly shortened, and efficient operation becomes possible. When performing contactless communication with multiple data recording devices 101, 102, and 103 simultaneously, contactless power supply and contactless communication may be performed at the same time. In this case, for example, a non-contact communication signal such as a drive control signal is superimposed on a non-contact power supply signal, which is an alternating current signal with a constant amplitude and frequency, to generate a composite signal, which is transmitted from the first antenna, and transmitted from the second antenna. The received composite signal is demultiplexed by the drive control unit and separated into a contactless power supply signal and a contactless communication signal, which can be used respectively. Further, the contactless power supply and the contactless communication may be performed in a time-sharing manner within an extremely short period of time that can be regarded as almost simultaneous, for example, about 10 μsec (microseconds) to 1000 μsec. Non-contact power supply and non-contact communication are performed, for example, when radio waves (electromagnetic waves) transmitted from a first antenna generate an induced current in a second antenna due to electromagnetic induction. In addition, non-contact communication in the opposite direction to the above is performed when radio waves (electromagnetic waves) transmitted from the second antenna generate an induced current in the first antenna due to electromagnetic induction.

The data recording device 100 of the data storage system 300 may further include a sensor section including a sensor element. The sensor element may include at least one of a pH sensor element, a temperature sensor element, an electrical resistance sensor element, and an image sensor element. Further, the sensor element may include at least one of a pressure sensor element, a magnetic sensor element, a humidity sensor element, a chromaticity sensor element, an illuminance sensor element, and the like.

The sensor section can be used to detect the state of an object to be measured in the container, such as a cell culture solution, cells, etc. The sensor unit may be installed inside a container, such as a petri dish, flask, or multiwell plate. The shape, size, etc. of the container are not particularly limited, but may have one or more spaces suitable for cell proliferation, for example. For example, a petri dish has a width or diameter of several centimeters to several tens of centimeters, and a height of several millimeters to several centimeters, while a flask has a width or diameter of several centimeters to several tens of centimeters, and a height of five centimeters to several tens of centimeters. In the case of a multi-well plate, the width or diameter is about several cm to several tens of cm, and the height is about 0.5 cm to several cm. The container may be made of an optically transparent material, such as plastic, glass, etc., so that the interior can be viewed from the outside.

Further, in a multi-well plate, the planar shape of one well is circular, quadrilateral such as square, polygonal such as pentagon, hexagon, etc. A circular shape is suitable for isolegal growth of cells, and has the advantage that cells can easily grow. The hexagonal shape is suitable for close-packed arrangement of wells and is advantageous for downsizing multiwell plates.

More specifically, the container may be a commercially available cell culture container, such as a cell culture plate, a cell culture flask, or a cell culture dish. These cell culture containers are equipped with lids and may be realized by injection molding of transparent resin.

Preferably, the container has a plurality of accommodating portions each having a cylindrical shape, an inverted partially conical shape, or the like for accommodating a liquid, for example, a culture solution. The sensor part may be installed inside or outside the container without containing cells and culture medium, and then the sensor part may be supplied with cells and culture medium. A section may be installed. Once the cells have grown sufficiently, the sensor section can be removed from the container, and the sensor section can be installed again after the cells and culture solution have been collected, washed, and sterilized.

Alternatively, the communication device main body 200 may be installed outside the container, and the data recording device 100 and the sensor section may be installed inside the container. For example, the communication device main body 200 may be provided so as to contact the external bottom surface of the container, and the data recording device 100 and the sensor unit may be provided so as to contact the internal bottom surface of the container. This allows the first antenna of the data recording device 100 to be placed close to the second antenna of the communication device main body 200. This suppresses the attenuation of signals such as feed waves, sensor element control signals, and detected data signals that are transmitted and received between the first antenna and the second antenna, and also reduces the mixing of noise into the signals. This makes it possible to receive signals with high reception strength. Further, a first adsorption device comprising a magnet, a magnetic layer, an adhesive layer such as a silicone resin layer, etc. is provided on at least a portion of the second surface (the lower surface facing the container) of the first substrate constituting the data recording device 100. A second adsorption member made of a magnet, a magnetic layer, an adhesive layer such as a silicone resin layer, etc. may be arranged at a location corresponding to the first adsorption member on the bottom surface of the container. In this case, the position of the data recording device 100 relative to the container can be reliably fixed, and even if the container vibrates during transportation, it is possible to prevent the data recording device 100 from shifting its position.

Further, for example, since the data recording device 100 does not come into contact with a corrosive measuring object such as an acidic culture solution, the durability of the data recording device 100 is increased and its lifespan is extended. For example, the data recording device 100 and the sensor section may be arranged on the inner side of the container, in which case it becomes easy to observe (monitor) the inside of the transparent container from above and below.

The first substrate on which the data recording device 100 is placed and the second substrate on which the communication device main body 200 is placed have protection made of silicon oxide (SiO ₂ ), silicon nitride (Si ₃ N ₄ ), etc. on their side surfaces. Layers may be arranged. In this case, when the side surface of the substrate comes into contact with the inner surface of the container, damage such as abrasion and chipping can be prevented from occurring on the side surface of the substrate, especially the corners of the substrate, and the object to be measured such as the culture solution in the container can be prevented. It is possible to prevent unnecessary objects such as fragments of the board from entering. Further, the protective layer disposed on the side surface of the substrate may have an extension portion extending to at least one of the first surface and the second surface of the substrate. This improves the effect of protecting the corners of the substrate. Alternatively, the insulating layer disposed on at least one of the first surface and the second surface of the substrate may extend to the side surface of the substrate to serve as a protective layer, and in that case, the corners of the substrate are also protected. The effect of

A silicone resin (silicone rubber) layer or the like is provided on at least a portion of at least one of the first surface (the upper surface and the surface on the bottom side of the container) of the second substrate constituting the communication device main body 200 and the bottom surface of the container. An adhesive layer, or a double-sided tape formed by coating or printing an adhesive on both sides of a tape such as a plastic tape, or the like may be disposed. In this case as well, the same effect as above is achieved. Furthermore, this adhesive member preferably has translucency. This makes it easy to observe the inside of the container from the outside. The adhesive force of silicone resin is due to the effect of the silicone resin having a fine network structure biting into the fine irregularities on the surface of the object to be adhered to, the attraction force due to molecular contact such as intermolecular force and van der Waals force, caused by Moreover, the adhesive is suitable because it has a high effect of biting into the fine uneven surface of the surface of the object to be adhered.

It is preferable that the first adsorption member, the second adsorption member, and the adhesive member described above are arranged at a portion that does not overlap at least one of the first antenna and the second antenna. In this case, the attenuation of signals such as power feeding signals, sensor element control signals, and detection data signals transmitted and received between the first antenna and the second antenna is suppressed, and the mixing of noise into the signals is reduced. This makes it possible to receive signals with high reception strength. More preferably, the first adsorption member, the second adsorption member, and the adhesive member are arranged at a location that does not overlap both the first antenna and the second antenna.

In addition, because the substrate is disc-shaped, a circular storage space can be created in a plan view suitable for isotropic growth of cells, such as in a cell culture plate, a cell culture flask, or a cell culture dish. Can be used appropriately in containers with The shape of the container is preferably cylindrical or inverted partially conical, which are suitable for isotropic cell growth. In particular, a container with an inverted partial cone shape is suitable for three-dimensional and isotropic cell growth.

The type of cells is not particularly limited, and may be animal cells, plant cells, yeast cells, bacterial cells, etc. Examples of animal cells include muscle cells, visceral cells such as liver, blood cells such as lymphocytes, monocytes, and granulocytes, nerve cells, immune cells, iPS cells (induced pluripotent stem cells), and the like.

These cells may be tissue-derived primary cells or may be subcultured cells. Note that iPS cells can be differentiated into cells of various tissues and organs, such as ES cells (embryonic stem cells), by introducing several types of genes into somatic cells such as human skin and culturing them. They are cells that have pluripotency and the ability to self-renew and maintain this ability even after undergoing division and proliferation, that is, the ability to proliferate almost indefinitely.

Further, the cells may be stem cells suitable for regenerative medicine, and the stem cells may be pluripotent stem cells such as the above-mentioned iPS cells, or somatic stem cells such as mesenchymal stem cells (MSCs). good. Mesenchymal stem cells are one type of stem cells that humans have, and are present in various locations throughout the body, including bone marrow, fat, and skin. Mesenchymal stem cells are cells that can differentiate into fat, bone, and cartilage, and can also differentiate into tissue cells such as hepatocytes and nerve cells. Mesenchymal stem cells include those derived from bone marrow and those derived from fat. Mesenchymal stem cells have an advantage over iPS cells in that they have immunoregulatory functions that prevent rejection reactions even after transplantation. Mesenchymal stem cells also have the advantage of having a low risk of tumorigenesis. Therefore, the cells may be mesenchymal stem cells, which are more suitable for regenerative medicine.

The data storage system 300 of this embodiment can be suitably used for managing the number of iPS cells that have a high proliferation ability. Furthermore, the cells may be prokaryotic cells such as E. coli cells, or eukaryotic cells such as animal cells or plant cells. The cell may be, for example, a normal cell or an abnormal cell such as a tumor cell, or may be an artificially produced cell such as a cell into which a gene has been introduced. Furthermore, the cells may be cells that are cultured as part of a living tissue. Cell culture may be adherent culture or suspension culture.

For example, the sensor element may measure the pH value, temperature, etc. of an object to be measured, such as a liquid in a container. The object to be measured is not particularly limited, but may be a culture medium for cell culture, and the culture medium may be a liquid such as a culture medium, a gel, a jelly, a semisolid substance such as agar, or a solid substance. It's fine. The liquid may be, for example, a buffer solution or a culture solution, and a commercially available cell culture medium can be used, and is selected depending on the cells used. The culture medium provides a growth environment for the culture target in the cultivation of biological tissues such as microorganisms and cells, and contains carbon sources such as glucose, nitrogen sources such as peptone and ammonium sulfate, amino acids, vitamins, phosphates, etc. It is a source of nutrients such as inorganic salts. It also provides a scaffold (base for proliferation) necessary for cell proliferation. Specifically, the culture medium includes a liquid medium consisting of a liquid containing the above-mentioned nutritional components necessary for cell culture, or a solid medium obtained by adding agar, gelatin, etc. to the liquid and solidifying it. The culture solution may also be Dulbecco's modified Eagle's medium, for example, when culturing mammalian cells. The culture solution may further contain components necessary for culturing cells, such as bovine serum albumin, growth factors, amino acids, antibiotics, and the like.

<Data storage method>

If contactless communication between the module 10 and the second communication module 50 is possible, the configuration is such that data transmission from the first communication module 10 to the second communication module 50 is started.

Furthermore, as shown in FIG. 3B, in the data storage method of the present disclosure, when the data storage system 300 includes a plurality of data recording devices 101 to 103, the data storage method of the present disclosure searches the plurality of data recording devices 101 to 103 at predetermined intervals. It is determined whether or not non-contact communication is possible, and a data transmission start request signal is sent to the first communication module 10 of the data recording device determined to be capable of non-contact communication among the plurality of data recording devices 101 to 103. It may further include a second control step A2 for controlling the second communication module 50 to transmit the second communication module 50, and a second storage step A4 for storing data, time information, and ID information received by the second communication module 50. .

Hereinafter, the data accumulation method of the present disclosure will be explained in order. Note that the data recording device, the communication device main body, the first communication module 10, the second communication module 50, the first storage units 20 to 23, the second storage unit 60, the first control unit 30, the second control unit 70, and the data transmission The start request signal, data, time information, and ID information are the same as those in the data storage system 300 of the present disclosure, so descriptions thereof will be omitted.

The first storage step A1 of the present disclosure is a step of storing data to be transmitted from the first communication module 10 to the second communication module 50. For example, the first storage step A1 is performed by the first storage unit 20.

In the second control step A2 of the present disclosure, a plurality of data recording devices 101 to 103 are searched at predetermined intervals to determine whether contactless communication is possible, and among the plurality of data recording devices 101 to 103, The second communication module 50 is controlled to transmit a data transmission start signal to the first communication module 10 of the data recording device determined to be capable of non-contact communication. For example, the second control step A2 is performed by the second control section 70.

The first control step A3 of the present disclosure controls the first communication module 10 to start transmitting data from the first communication module 10 to the second communication module 50 based on the data transmission start request signal. In the first control step A3, when the first communication module 10 receives a data transmission start request signal from the second communication module 50, it may be determined that non-contact communication is possible. In the first control step A3, if contactless communication is possible, the first control step A3 is configured to transmit at least one of time information and ID information regarding data transmission from the first communication module 10 to the second communication module 50. 1 communication module 10 can be controlled. For example, the first control step A3 is performed by the first control section 30.

The second storage step A4 of the present disclosure stores data, time information, and ID information received by the second communication module 50. For example, the second storage step A4 is performed by the second storage unit 60.

The data storage system of the present disclosure can be applied to various communication systems. For example, in addition to the above-mentioned cell culture state management system, examples include telephone communication systems such as telephone communication, image communication systems that transmit and receive various images such as medical images, satellite communication systems that transmit and receive information such as meteorological satellites, aircraft, ships, etc. A route communication system that sends and receives route information, a traffic management system that sends and receives information such as the number of cars traveling, and traffic congestion information, a train management system that manages the speed and location of trains, subways, etc., and products that send and receive information such as product sales volume. management system, a traffic monitoring system that monitors the amount of pedestrian traffic, etc., a safety management system that sends and receives disaster information, crime information, etc. from surveillance cameras, a cropping management system that sends and receives information such as the planting status of cultivated land using drones, etc. There are also natural environment monitoring systems that transmit and receive information on natural environments such as forests and oceans using drones and other devices.

According to the data storage system of the present disclosure (first disclosure), since it is configured as described above, there is a period during which the first communication module of the data recording device and the second communication module of the communication device main body cannot communicate without contact. Even if contactless communication becomes possible, data can be automatically transmitted from the first storage section of the data recording device to the main body of the communication device by contactless communication. As a result, even if the communication environment does not always allow contactless communication, once the communication environment allows contactless communication, data can be automatically transmitted from the data recording device to the main body of the communication device. Therefore, it is possible to save the worker the trouble of manually transferring data. Furthermore, it is possible to save the worker the trouble of continuously monitoring and periodically checking the capacity status of the internal memory of the data recording device.

Further, according to the data storage system according to another aspect of the present disclosure, the data transmission start request signal is configured to be transmitted from the second communication module to the first communication module, and the first control unit: When the first communication module receives the data transmission start request signal, it determines that non-contact communication is possible. That is, when transmission and reception is established in which the second communication module transmits a data transmission start request signal requesting the first communication module to start data transmission, and the first communication module receives the data transmission start request signal. Determine that contactless communication is possible. As a result, depending on the non-contact communication status between the first communication module and the second communication module, the first storage section stores data independently or transfers data from the first storage section to the main body of the communication device. It becomes possible to automatically determine whether

Further, according to the data storage system according to another aspect of the present disclosure, the second communication module periodically transmits the data transmission start request signal to the first communication module, so that the second communication module periodically transmits the data transmission start request signal. can be done. This facilitates transmitting data from the first communication module to the second communication module before the capacity of the internal memory of the data recording device overflows.

Further, according to the data storage system according to another aspect of the present disclosure, the first communication module transmits data to the second communication module when the first communication module is in a communication environment in which it can receive the data transmission start request signal. It becomes easy to determine whether contactless communication is possible in the first communication module. That is, even if the second communication module issues a request to start data transmission, as long as the first communication module does not receive the data transmission start request signal, erroneous data transmission can be avoided.

Further, according to the data storage system according to another aspect of the present disclosure, a plurality of data recording devices may be provided, and the communication device body searches the plurality of data recording devices every predetermined period to perform contactless communication. contactless communication is possible, and transmits a data transmission start request signal to the first communication module of the data recording device that is determined to be capable of non-contact communication among the plurality of data recording devices. Since it further includes a second control unit that controls two communication modules, it selects a non-contact communicable data recording device that is capable of non-contact communication from among the plurality of data recording devices, and It becomes possible to automatically transfer data stored in the first storage unit to the second storage unit of the communication device main body. Further, even if a data recording device is once unable to perform contactless communication, if contactless communication becomes possible after a predetermined period of time has elapsed, data can be automatically transferred.

Further, according to the data storage system according to another aspect of the present disclosure, the first storage unit stores time information regarding data transmission and ID information of the data recording device, and the first control unit stores the contactless When it is determined that communication is possible, the first communication module is controlled to transmit at least one of time information and ID information from the first communication module to the second communication module. Data can be easily searched on the communication device main body side based on at least one of the ID information.

Further, according to the data storage system according to another aspect of the present disclosure, the second storage unit that stores the data, time information, and ID information received by the second communication module is further provided. Even after the time has elapsed, data can be easily searched on the communication device main body side based on at least one of the time information and the ID information stored in the second storage unit.

Further, since the data storage system of the present disclosure (second disclosure) has the above-described configuration, the first control unit is configured to respond to the data transmission start application signal transmitted from the data recording device to the communication device main body by the communication device. If the main unit gives permission to start data transmission, it is determined that contactless communication is possible. For example, if a transmission/reception is established in which the first communication module transmits a data transmission start application signal requesting to start data transmission to the second communication module, and the second communication module receives the data transmission start application signal. Determine that contactless communication is possible. As a result, depending on the non-contact communication status between the first communication module and the second communication module, the first storage section stores data independently or transfers data from the first storage section to the main body of the communication device. It becomes possible to automatically determine whether That is, even if the communication environment does not always allow contactless communication, once the communication environment allows contactless communication, data can be automatically transmitted from the data recording device to the main body of the communication device. Therefore, it is possible to save the worker the trouble of manually transferring data. Furthermore, it is possible to save the worker the trouble of continuously monitoring and periodically checking the capacity status of the internal memory of the data recording device.

According to the data storage method of the present disclosure, since it includes the above-described steps, even if there is a period in which the first communication module of the data recording device and the second communication module of the communication device main body cannot communicate without contact, the data storage method of the present disclosure can once communicate without contact. If this becomes possible, it will be possible to automatically transmit data from the data recording device to the main body of the communication device via non-contact communication. As a result, even if the communication environment does not always allow contactless communication, once the communication environment allows contactless communication, data can be automatically transmitted from the data recording device to the main body of the communication device. Therefore, it is possible to save the worker the trouble of manually transferring data.
